I thought I’d give it a shot manually instead, so I followed this: http://www.studiopress.com/forums/topic/learning-genesis-custom-header-image/ and this http://blogominded.com/2011/12/how-to-insert-a-custom-logo-in-genesis-framework-child-themes/ , after an unsuccessful attempt (the logo appeared misaligned with the menu by a few inches) I reversed back to the default executive codes only to find the Title text now overlaps the image and refuses to go away whether I untick the “Header Text” box or not.
